The washing machine comprises a display module and a sound module, wherein the display module emits the lights of different colors according to the different washing states of the washing machine; the sound module produces the different sounds according to the different washing states of the washing machine; and the display module and the sound module simultaneously control the lights and the sounds to correspond to the washing states by a central processing unit (CPU) of a computer program controller. According to the different washing states, the backlights of different colors are emitted and the music with different kinds of frequency is produced, so a user can clearly know the running states of the washing machine, and can know the running state of the washing machine without walking to the washing machine according to the frequency of the music; moreover, noises produced by the washing machine can be compensated by adopting the corresponding music frequency, so the user can conveniently, easily and pleasantly wash clothes by using the washing machine.
